LOOM` FOR WEAVING FIGUREDIDOUBLE PILE FABRICS.

SBECIEICATION forming part of Letters Patent No. 354.358, dated December14, 1886. Y

Application filed May 27, 1886.

To all whom it may concern:

Be it known that I, TOM I. SHUTTLEWORTH, a citizen of the United States,residing in Amsterdam, Montgomery county, New York, have inventedcertain Improvemehts in Looms for Weaving Figured Double Pile Fabrics,of which the following is a specification.

My invention relates to looms for weaving gured double pile fabrics, myinvention con- 1o sisting in certain novel means for operating thepile-threads, whereby on the rise of the Jacquard lifter-board anydesired pile-thread may be drawn down from the upper warp into the lowerfabric or drawn up from the lower warp into the upper fabric, so as toproduce two fabrics having a corresponding figure.

In the accompanying drawings, Figures 1, 2, and 3 are diagramsillustrating the method of weaving the fabric in accordance with my 2oinvention, Fig. 4, adiagram showingsufcient of a loom to give a properunderstanding of my invention; Figs. 5 and 6, diagrams illustrating theoperation of the heddles controlling the ground-warp threads; Figs. Zand 8, 2 5 diagrams illustrating the operation of the harnesscontrolling the pile-warp threads, and Figs. 9 and 10 are viewsillustrating modifications of my invention.

Each of the fabrics has a number of pile- Warps, x, and two ground orbacking threads, y, the number of pile-warps depending upon the numberof colors in the pattern to be produced.

The operation of weaving the fabric will be understood upon reference toFigs. 1, 2, and 8. In Fig. l the threads are represented as they appearafter the figuring pile-warps have been drawn from the upper to thelower and the lower to the upper fabric and bound 4o in by thefillingshots 1, all of the upper pile- Warps being then elevated and thelower pile- Warps depressed and the ground or backing warps of eachfabric crossed, so as to form upper and lower'sheds for the insertion ofthe binding-shots 2, which are thrown in and beaten up and theground-warps of each fabric then again crossed, as shown in Fig. 2, toform sheds for the bindingshots 3, and after throwing in these shots theground-warps of 5o each fabric are again crossed to form upper SerialNo. 203,412. (No model.)

and lower sheds, all of the upper pile-warps except those for the figurebeing lowered to the level of the bottom of the upper shed, and all ofthe lower pile-warps except those for the gnre being raised to the levelof the top of the lower shed, as shown in Fig. 3. Such of the upperpile-warps as are necessary to form the figure are drawn down into thelower shed, and such ofthe lower pile-warps as the figure demands arelifted into the upper shed, as shown in Fig. 3, preparatory to throwingin the binding-shots 1, which con-l reels from which the pile-warps :rare drawn,-

g/ the beams which supply the upper and lower ground-warps, c a theheddles for operating said ground-warps, and b b heddlesv for operatingthick fillingor stuffing warps w, which are drawn from beams w. Thesestuffing-warps alternate with the sets of pilewarps x, thelatter and thestufiingwarp preferably passing through alternate dents in the reed.

The heddles a a have double eyes, as shown in Figs. 5 and 6, the threads'y of t-he upper fabric passing through the upper eyes of the heddlesand the threads y of the lower fabric through the lower eyes, these eyesbeing so related and the lift of the `heddles being such as to effectthe proper formation of the upper and lower sheds.

Each of the pile-warps x is controlled by a harnessthread connected toone of the needles d of the jacquard and passing through the usualnotched eye in a lifter-board, f, above said jacquard-needles, eachharness.- thread having a knot above the lifter-board, so that when thethread is adjusted by the needle .so as to bring this knot over a notchof the board ksaid knot and that portion of the thread in ICO y which,inthe presentinstanceLacts upon knots upon the harness-threads of thepile-warps of the lower fabric, while the lower board acts upon knotsupon the harness-threads of the pile-warps of the upper fabric, andthese boards are caused to move toward and apart from each other, sothat on the rise of the upper board, g, all of the pile-warps of thelower fabric, except the iigure-warps, will belifted from the positionshown in Figs. 1 and 2 to that shown in Fig. 3, the descent of thelowerboard, h, causing the corresponding pile-warps of the upper fabricto drop to the same extent. The ,comber boards remain separated whilethe binding-shots 1 are being thrown in, after which they are drawntogether, so as to restore the warps under their control to thepositions shown in Figs. 1 and 2.

Such of the pile-warps as are desired to forni the figure are by meansof the j acquard brought under control of the lifter-board, which has amovement in excess of that imparted to the comber-boards, so that saidfiguring pile-warps will be carried up or down into the opposite fabric,as set forth in the beginning of the specification.

The figuring-threads ofthe lower pile-warp are simply elevated by theaction of the lifterboard as the latter rises in the usual manner but itis necessary to transform this rising movement ofthe lifter-board into adownward movement of the f1 guring-threads'of the upper pile-warp; hencein accordance with one plan of carrying out my invention I pass each ofthe harness-threads of said upper pile-warps around a pulley, z', orother bearing, double it back upon itself, pass it again through the eyeof the lifter-board, and connect it at the lower end to a strip, m, ofrubber or other elastic material, secured to the guide-board n below theJacquard apparatus, or to any other available point of connection. Thelifter-board acts upon a knot on this returned portion of theharness-thread, so that the lift of the board serves to stretch thespring and permit the drop of the weighted portion of the harnessthreadwhich controls the warp-thread, said warp-thread being lifted on thedescent of the board by reason ofthe contraction of the spring m, whichexerts a force considerablyin excess of the weight. These operationswill be understood on reference to Figs. 7 and 8.

The lifter-board of the jacquard is operated by a cam, 1, on a shaft, 2,the cam acting on a slide, 3, which is connected by a rod, 4, to alever, 5, connected to the lifter-board by a rod, 6.

The comber-boards are operated by a cam, 7, on theshaft 2, this camacting on a slide, 8,

which is connected by a rod, 9, to a lever, 10, and by a rod, 11, to anarm, 12, the lever 10 being connected by a rod, 13, to the uppercomber-board, g, and the arm 12 by a rod, 14, to the lower comber-board,7L, so that the desired movements of said boards toward and from eachother are e'ected,

The Jacquard cylinder, heddles, lathe, takeup rolls, camshaft, and otherparts of the loom may be operated by mechanism, which need not bedescribed, as it forms no part of my invention. I may say, however, thatthe patent of Bigelow, No. 16,870, January 13, 1857, shows mechanismwhich is available for the purpose.

In the modification of my invention shown in Fig. 9 the harness-threadswhich control the pile-warps of the upper fabric are doubled at thelower end instead of at the upper end, and pass round rollers t',carried by a bar secured to the frame of the loom. In this case the knotis on the main portion of the harness thread, above the lifter-board,and the eye for the warp-thread is on the returned portion of saidharnessthread, t-he upper end of which is connected to the elastic cordm, so thaton the rise of the knot under the action of the lifterboardthe harness-eye will be depressed and the spring m stretched. But onecomber-board is used in this ease, said board having eyes for bothportions of the doubled harness-threads.

It will be evident that a weight may take the place of a spring as ameans of maintaining the returned portion of the harness-thread in itsnormal position; but the spring is preferred. It will be evident, also,that my invention can be used in connection with Jacquard apparatus ofthat class in which lifterbars f are used in place of an eyed andnotched lifter-board, and lifter-hooks s are used instead of knots inthe harness. (See Fig. 10.)

I claim as my invention- 1. As a means of drawingaplethread from theupper to the lower fabric in weaving gured double pile fabrics, thecombination of a lifter board or bar and operating mechanism thereforwith a harness-thread having a doubled or turnedback portion withelastic or weighted end, that part of said thread on one side of theturn having the knot or equivalent device for the action of the lifterboard or bar, while that portion of the thread on the other side of theturn has the eye for the passage of the warp-thread, all substantiallyas specified.

2. The combination, in a loom for weaving figured double pile fabrics,of the Jacquard lifterboard, its operating devices, and the straightharness-threads controlling the pilewarps of the lower fabric,withharness-threads controlling the pile-warps of the upper fabric, and eachhaving a doubled or turned-back portion with elastic or weighted end,all substantially as specified.
